Dear Kim Vong, You just confirmed what I didn't know before. Instead of using cell phone, I use coconut phone : it emits very small radiation but you need to speak louder.

Dear all, Like it or not, cell phones have become an integral part of everyday society for millions of people. In the United States alone, 250 million people have cell phones. When you take the rest of the world into account, you're looking at over five billion cell phone users. It's hard to believe that not all that long ago these phones were considered luxury items! The craziest part is, even though we've written about the effects of cell phone radiation on brain tissue before, scientists still don't know the extent to which cell phone use may effect our brains. Now, a new study has proven unequivocally that the radiation emitted from cell phone antennas alters our brain activity. While these effects may not necessarily be harmful, it's impossible to argue any longer that cell phone usage has no physical impact on brain tissue. The research, which took place through the National Institutes of Health in Bethesda, Maryland, focused on the brain's increased metabolism of glucose while using a cell phone. The 47 study volunteers underwent PET scans while holding cells phones to their heads that were either off or on but muted. The scientists discovered that more than 50 minutes of exposure to a cell phone that is on boosts activity in the area of the brain nearest the antenna by approximately seven percent. The amount of electromagnetic radiation coming off of a cell phone is relatively small, but this study was designed to pick up even small changes in brain metabolism. And it leaves no question that the brain responds to the weak signals when they are in close proximity. Since it is only within the last 20 years that cell phone use has truly exploded, its long-term effects are as yet unknown, and the research performed to date is inconclusive as to exactly how much -- and what kind of -- damage we are causing when we use cell phones regularly. And use them regularly we do. Especially the under-30 segment of the population, for whom cell phones are the primary means of communication. More and more people are giving up landlines and only using cell phones, which means that many of us are using our cell phones for a good deal longer than the 50-minute threshold outlined in the study as the point at which our brain activity reacts to the radiation exposure. No one knows for sure whether this exposure can cause brain tumors or other abnormalities, at least in part because the vast majority of the studies on cell phone safety have been funded by none other than the cell phone industry. Nothing like an unbiased opinion, right? But even industry-funded studies have found significant increased risks of brain cancer and genetic damage, and that risk hovers around 20 percent for each accumulated year of cell phone use. Many cancer specialists and neurosurgeons take precautions themselves with cell phones and recommend others do the same. Do some research and purchase a phone with low radiation emission; use a Bluetooth or other hands-free device such as a wired earbud with a built-in mic even when you're not driving; don't use your cell phone when you have a weak signal; limit the time your children use cell phones, since they are more vulnerable to the radiation; use the speaker instead of holding the phone to your ear; and text instead of calling -- but never when driving a car. These suggestions may not eliminate the risk, but will hopefully provide enough protection to keep our brains safe.
